version 8.5 cannot edit time and date of multiple photos
mac, desktop lighroom app.
select multiple photos
photo -> edit date & time
"1 photo" shown in upper right and clicking change will only change that photos time, intead of all photos
Do you mean you see "1 photo" in the red circle, even when multiple photos are selected? As you can see in my screenshot, I can't reproduce that on my Mac. Do make sure you are in grid view however. If you are viewing only one photo, then indeed only that one photo will be changed. That is by design, to avoid mistakes because you may not realise you still have multiple photos selected.
